We were going to Gourdough's to get some big fat doughnuts. Yay for big fat doughnuts!

But on our way, we were sidetracked by something heaven-sent: Holy Cacao. If you're not familiar with the way the food truck scene is set up in Austin, Texas, let me tell you that it is epic. In my opinion, it's like Portland's food truck scene, but like, times ten. There are food truck "pods" or mini communities, set up in lots all over. Some even have communal seating areas. It makes for a really friendly atmosphere and really promotes trying products from multiple vendors.

And while exploring other vendors on our way to Gourdough's, this was the one that caught this Spy's eye. Specializing in chocolate and cake pops, it was right up my alley. Even more so when I noticed their tag line: Las cosas claras y el chocolate espeso." (Ideas should be clear and chocolate thick.) - Spanish proverb. I like that way of thinking.

You should probably get one of everything here. They offer cake balls in all sorts of flavors, shakes (including! A cake shake!), and drinking chocolate. And it's the drinking chocolate that is the base of their Frozen Hot Chocolate.

If you have never heard of frozen hot chocolate, let me educate you. It's an incredibly rich chocolate base that is then mashed with ice cream and ice and blended to smooth, creamy confection perfection. It's not quite a milkshake, but it's more than just chilled hot chocolate. When done poorly, it's like a grainy coolatta. When it's done well, it's magic. It's famous the world at a place called Serendipity 3 in New York City.

At Holy Cacao, they do it right. You start by choosing a hot chocolate flavor - Holy, Cacao, The Mexican, or Peppermint Patty, and then they will blend it with ice and Blue Bell Dutch Chocolate Ice Cream (because in Texas, you're in Blue Bell country), carefully adjusting their blender and mashing down uncrushed ice and blending again to ensure the correct consistency. What you get is, as they aptly declare on their website, "a rich, chilled chocolate experience."

My companion, who grew up in New York City with Serendipity 3 as the guiding light and standard of what a Frozen Hot Chocolate can and ought to be, not only approved, but (watch out) declared it superior. And I can agree that it is very, very, very good.

It doesn't really get so cold in Austin, it more trends toward hot, and this beverage is the perfect way to cool down, deliciously.
